HAY-CARRIER.

Specification of Letters Patent.

.Fa-touted Oct. 4, 1910.

Application filed `Tuly 27, 1909. Serial No. 509,808.

To all whom "it may concern:

Be it known that we, HENRY L. FERRIS and HOWARD J. Farris, citizens ofthe United States, residing at Harvard, in the county of McHenry andState of Illinois, have invented a new and useful Improvement in Hay-Carriers, of which the following is a specification.

Our invention relates to certain new and useful improvements in haycarriers, and is fully described and explained in the specification andshown in the accompanying drawings, in which- Figure l is a sideelevation of our improved device; Fig. 2 is an end view of the same;Fig. 3 is a transverse section in the line 3 of Fig. l; Fig. et is asimilar view showing the parts in a different position; Fig. 5 is asection in the line 5 of Fig. 3; Fig. 6 is a perspective view of theclampingmember; Fig. is a perspective view of the dog, and Fig. 8 is asection in the line 8 of Fig. 2.

Referring to the drawings-A is a track such as is in common use forhay-carriers, B, B, are the two halves of a carrier which are connectedtogether by a right and left threaded bolt Bl whereby their distanceapart may be adjusted for tracks of various widths. rllhe halves B ofthe carriage support at their ends pulleys l) which run upon the track Ain the usual manner. The bolt B1 furnishes pivotal support for a frameC, which, it will be observed lies in a plane transverse to that of thetrack. Within this frame is rotatably mounted a sheave C1 over whichruns the hoisting-rope D, the bight of which carries sling-pulleys ofthe usual form, and the end of which is attached in usual manner to alug c on the frame C. lithin the frame C, and straddling the sheave C1is a clamping-member E, the shape of which will be best understood byreference to Fig. 6. The clamping-member has laterally projecting flatstuds e, which extend through holes in the frame C, the holes beingsomewhat larger than Jthe studs and each having a flat side asillustrated in the drawings, to cooperate with the fiat portions of thestuds e to hold the clampingmember in a fixed position under certaincircumstances as will hereafter be set forth. The clamping-member alsohas two projecting pins el at its lower end, which said pins areattached to links F, surrounded by springs j' which tend to draw theclampingmember bodily toward the center. The springs f, it will benoted, are for convenience and compactness of construction, mounted inoscillatory barrels f1.

The result of the foregoing construction is that the clamping-member canoccupy alternatively either the position shown in Fig. 4, or theposition shown in Fig. 3. When in the position shown in Fig. 4, thearched upper portion of the clamping-member is out of contact with therope, and the pressure exerted by the springs -7" upon theclamping-member through the medium of the links F, which in thisposition lie below a straight line connecting the pivot of the barrelsf1 with the studs e, will hold it so, but when the clamping-member ismoved slightly it will be swung forward, in which position the archedupper part of the clamping-member will Contact with the rope. It is tobe noted that when in the position shown in Fig. Il, or in the unlockedposition, the clamping-member is held stationary by two different forces:-first, the action of the springs acting in a line below thedead-center and second, the engagement of the fiat parts of the studswith the fiat parts of the holes in the frame. For the purpose ofoscillating the clamping-member to secure the desired clamping-action, adog G is provided, the said dog` being pivotally mounted on a stud e2projecting from the clamping-member along its forward edge and above thestuds e which form the pivot thereof on the frame. This dog it will benoted while cast in one piece has two portions which are off-set withrespect to each other, so that the rear end of the dog lies outside thecase or frame as shown in Fig. 2, while the forfard end thereof liesinside the case or frame, as shown in Fig. 5, the case or frame beingslotted to provide for the entrance and movement of the dog. The dog isprovided with a spring g by which it is normally given a tendency tocross-wise rotation as viewed in Fig. 2. The inner, or forward, end ofthe dog is so positioned as to engage with a ratchet H mounted upon andrigid with (preferably integral with) the sheave C1. A hand-rope G1extends from the rear or outer end of the dog, by which the same can berotated against the pressure of the spring when desired.

The frame C is provided with eyes I to which are attached ropes 11,through the medium ot which the entire structure may be moved along thetrack as desired.

The operation of my device as a whole will now be set fort-h.

The device in its normal or unlocked position is shown in Fig. et, whichis the position which it occupies when a load is about to be lifted. ltwill be understood that in this position, the sling-pulleys are engagedwith the hay-sling in the usual manner, and the main hoisting-rope isoperated to raise the load. The moment the tension upon the load isreleased, the sheave will begin to rotate in the reverse directionwhereupon the ratchet thereon will engage with the inner or forward endof the dog drawing the same with it in its rotary movement and pullingthe locking-member down into the position shown in Fig. 3, whereupon thesame will engage the rope and clamp it firmly between itself and thesheave. The carrier can then be drawn to any desired position and theslings released and the carrier returned. When it is desired to drawdown the sling-pulleys again for a second operation, the hand-rope G1 ispulled downward forcibly, with the result that the dog is released fromthe ratchet and rotates thc locking-member back to the unlocked positionindicated in Fig. et, in which position the locking-member remainsfixed. Buring the downward pulling of the main-rope, the hand-rope G1will, ot1 course, be held taut to prevent the locking-device from againswinging into locking position.

It will be seen that this device is exceedingly simple in construction,comprising few parts and that it can be made very light in weight.Furthermore, the total height of the device is small so that the loadcan be pulled very close to the track. rhe device is also readilyadjustable to different sizes o track in the manner indicated. Greatadvantages arise from the fact that the locking-member is heldpermanently away from the rope during the raising of the load and thatit is automatically7 swung positively against the same upon thecommencement of the descent of the load.

le realize that considerable variation is possible in the details ofconstruction of 'our improved device, without departing from the spiritof our invention, and do not intend, therefore, to limit ourselves tothe specific form herein shown and described.
